  1. i in loop = 0 i in loop = 1 i in loop = 2

  2. i in loop = 0 i in loop = 0 i in loop = 1 i in loop = 2

  3. i in loop = 0 i in loop = 2

  4. Compiler Error


Correct Option: C

package loop; public class TestLoop1 { void testFor() { for (int i = 1; i < 3; i++) { System.out.println("i in for loop = " + i); if (i == 1) { break; } } System.out.println("For loop over"); } public static void main(String[] args) { TestLoop1 tl = new TestLoop1(); tl.testFor(); System.out.println("Method call Over"); } }

  1. i in for loop = 1 i in for loop = 2 For loop over Method call Over

  2. i in for loop = 1 For loop over Method call Over
